Title: Transistor amplifier
Inventor: HASHIMOTO MASAAKI
IPC: H03F3/45
Filed: 1987-08-04
Abstract: PURPOSE:To increase a dynamic range and the gain together with improvement of the noise/frequency characteristics for a transistor amplifier, by using a parallel circuits of 1st and 2nd differential connection circuits and a 3rd differential connection circuit to differentially amplify the input voltage. CONSTITUTION:The 1st differential connection circuit consists of a transistor group QG1, a transistor (TR)Q1 and a constant current source CS1. The 2nd differential connection circuit consists of a TR group QG2, a TRQ2 and a constant current source CS2. Then the 1st and 2nd differential connection circuits are connected in parallel with each other. While the 3rd differential connection circuit consists of a TRQ3, a TRQ4, a constant voltage source VS, a TRQ5, a TRQ6 and a constant current source CS3. Then the input voltage is differentially amplified by a parallel circuit containing the 1st and 2nd differential connection circuits having large dynamic ranges. Furthermore the input voltage is differentially amplified by the 3rd differential connection circuit. As a result, the dynamic range and the gain are increased for a transistor amplifier together with improvement of the noise characteristics ensured since each differential connection circuit uses no emitter resistance. Furthermore the Miller effect is reduced or eliminated so that the frequency characteristics can be improved.

Title: Recovery cap for ink-jet recording head
Inventor: YASUDA JUNJI
IPC: B41J2/165
Filed: 1997-07-07
Abstract: PROBLEM TO BE SOLVED: To concentrate a pressure, a suction force of ink to a part of nozzles and obtain efficient recovery performance by butting a cap having a hole opened like a slantwise slit in a flat plate to an orifice face at the time of an ink recovery operation, and restricting a count of opened nozzles. SOLUTION: When ink is supplied from ink feed pipes 3, 4 and a pressure is applied, discharge openings 1 are shut by a flat plate 5 and ink is discharged from the discharge openings accommodated in a slit 6. At this time, when the air is present in nozzles of the discharge openings which can discharge ink thereby increasing a flow of ink, the ink tends to flow to nozzles of a lower flow resistance without the air. However, there is little escape for the ink and the pressure of the ink is increased, and therefore a sufficient pressure for discharging the air out of the discharge openings is obtained. A recovery cap 5 is moved in an up-down direction relatively to a recording head 2 to partially open all of the discharge openings to carry out a recovery operation.

Title: Pre-shifting circuit of write data
Inventor: UNO KOUJI
IPC: G11B20/10
Filed: 1982-11-10
Abstract: PURPOSE:To obtain a large amount of shift without using a high-speed logic element by providing a pre-shift logic deciding means which supplies the binary information and discriminate the mode of inversion of magnetization and a delaying means which shifts the binary information on the basis of the result of discrimination obtained by said logic deciding means. CONSTITUTION:When the binary information is supplied to a shift register 1, the acknowledgement output signals A, B and C of FF4, 7 and 10 are set as shown in the diagram. A combination logical circuit 2 is constituted so that the AND is satisfied for one of AND gates 11-15 by the conditions of other signals when a signal B is set at logic ''1''. Thus the AND conditions of the gate 15 are satisfied when a pre-shift properiety command CPM is set at logic ''0''. The AND conditons of the gate 11 and the gate 14 are satisified when the command CMP is set at logic ''0'' and at logic ''1'' with signals A anc C set at logic ''O'' respectively. In such a way, a delay element 26 is used in case no shift is given. The delay element is not used when signals C and A are at logic ''1'' and ''0'' respectively with the AND satisfied with the gate 12. As a result, an output 2 of the gate 12 is relatively accelerated by a degree equivalent to the amount of delay due to the element 26.
